IMPROVEMENT IN MOLE-TRAPS.

Specification forming part of Letters Patent No. 126,573, dated May 7,1872.

Specification describing an Improved Mole- Trap, invented by CLARKPOLLEY, of McMinnville, in the county of Warren and State of Tennessee.

The invention relates to that class of moletraps in which are employed atrigger, against which the upward pressure of the animal acts, a spikedslide which transfixes him, and a post which supports the trigger,slide, and operative mechanism. The invention consists of severalimprovements which Will first be fully described in connection with allthat is necessary to a full understanding thereof, and then clearlypointed out in the claims.

Figure 1 is a side elevation, partly broken out. Fig. 2 is a frontelevation of the post. Fig. 3 is a back View of the trigger.

A represents the post, B the spiked slide, and O the trigger. The post Aand the slide B are both provided with semi-tubular or channeled shanksa b on the inner side to embrace the trigger and operative mechanism,and are provided, also, respectively, with the flanges a and b on theoutside. By this construction I am enabled to apply a spiral spring, D,so as to not only impel the slide but to hold together all the parts,and to render them easily detachable by simply turning the spring untilit passes both the flanges a b. The post A is also constructed with thestuds 0. a a on the inside of channel, while the slide B has a lateralnotch or recess, W. E is a lever, beveled on one side so as to form theinclines c e, and pivoted in the stud a. O is the trigger, having theusual horizontal projection f, while f is one recess or notch in theside thereof to catch on stud a and f another recess to guide the upperend of trigger against stud M. f f are two inclined strips, which bear,respectively, against the inclines e e of lever E.

The mode of operation is as follows: The post A being made fast on sideof mole-path, with the projection f and spiked slide B over the saidpath, the trap is ready to be set. By drawing up the slide B on the postA and against the spring D, the upper end of lever E is pressed by theincline e to one side and into the notch b of slide B. This slide isthus held up against the tension of spring D until the lever isvibrated. This vibration is efiected by the animal, who presses againstprojection f, raises trigger 0, moves incline f against beveled end 0 oflever, and moves its upper end out of the notch b This allows the springto throw down the spikes vertically, so as to pierce the animal andspear him in his path.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The post A and slide B, having channeled shanks a b and flanges a I),combined with the spiral spring D, arranged and applied as and for thepurpose described.

2. The combination, with post A, slide B, and spring D, of the trigger Oand lever E, all constructed and arranged to operate in the mannerdescribed.
